I think I successfully asked the girl out today. After the training session was over I was talking to her and mentioned how it was a bummer that the sessions were over and we wouldn't be hanging out anymore because hanging out and training with her was really fun and she's chill and interesting, then I asked if she'd like to hang out with me sometime outside of the gym to which she said yes. I said awesome and said that I'd call her and she said cool and mentioned that I already have her phone number and can call her and she asked about my number because I had called her from 2 different numbers in the past so I gave her the correct number.
Obviously she could have a boyfriend or something and just think I was asking to be friends but it seemed pretty obvious I was asking her out (at least to me). I'm going to give her a call in a couple days to invite her out and hopefully then it'll be clear whats up; I'm hoping for the best because not often do I meet a smart, funny, interesting, attractive and close to my same age girl that is single and into me. If she does have a boyfriend that'd be a huge bummer because I'm really digging her but she'd still be a cool friend and would add to my list of girls that I am friendzoned with, my favorite zone of all
